Hm, strange... I do not remember doing anything else...

Who exactly is complaining about type mismatch?
gtk-button-set-label expects :gtk-string, and :gtk-string is :pointer,
not a Lisp string...

(defmethod cffi:translate-to-foreign (value (type (eql
:gtk-string)))          
  (when (null value) (setf value "")) ; pod
???                                
  (cffi:foreign-string-alloc value))

"The |foreign-string-alloc| function allocates a foreign string
containing a Lisp string or |(unsigned-byte 8)| array."

Sincerely yours,
